问题描述：
having finished the work,____
a.a postman came and delibered the evening paper and some letters
b.it was almost six o 'clock
c.supper had been already prepared
d.we had a rest and then had supper
这题答案选D可我选B 其实我觉得别的也对.我不知道这题要考什么哦,
答
这个当然应该选D，前面的状语从句省略了主语，换句话说，后面主句的主语要和前面的having相配，所以只有we和have是相配的，其它选项的主语都不对。
答
应该选D吧，主语要一致
答
要选D。
前句是无主语的现在分词，所以后面的句子中是肯定要有动作的主语的。所以B肯定是不行的。
你觉得B也行，是受了中文的影响。
答
考的是非谓语动词啊，只有前后主语一致时，从句才可以省略主语，由于having是现在分词，可以判断出主语和finish是主动关系，所以先去掉B和C，再根据意思判断，最终选D．
答
d.we had a rest and then had supper因非谓语动词作状语其逻辑上的主语和主句的主语必须一致,只有we可以作having finished the work的逻辑主语,故选D,而不选其它答案.
